M EASURING AND REGISTERING DEVICE.

SPECIFICATION forming part of Letters Patent No. 630,659, dated August8, 1899. Application filed June 13, 1898. Serial No. 683,315. (No modemTo all whom it may concern:

Be it known that I, EDWARD S. CLAYTON, a citizen of the United States,residing at Cornersville, in the county of Marshall and State ofTennessee, have invented new and useful Improvements in Measuring andRegistering Machines, of which the following is a specification.

This invention relates to measuring and registering machines, and hasfor its object to provide improved means whereby coffee, sugar, grain,and similar dry materials may be discharged from the stock in bulk andau tomatieally measured and the measurement indicated in pounds anddecimal fractions of a pound; and to this end it consists in the novelconstruction,combination,and arrangement of parts hereinafter described,and particularly pointed out in the claim following the description,reference being had to the accompanying drawings, forming a part of thisspecification, wherein- Figure 1 is an end elevation of a machineconstructed according to my invention. Fig. 2 is a vertical longitudinalsection; and Fig. 3 is a top plan view, partly broken away.

Referring to the drawings, the numeral 1 indicates a horizontal cylinderprovided at one end with a feed-hopper 2 and at its other end with adischarge-spout 3. The hopper 2 should be large enough to hold a bag ofcoffee or a barrel of sugar, and the d ischargespout should be ofsuflieient capacity to freely discharge the material without anytendency of the latter to choke in the spout. The rear end of thecylinder 1 is permanently closed, and its front end is closed by aremovable cap 4-,which is screwed onto the threaded end of the cylinder.Journaled in the opposite ends of the cylinder 1 is a shaft 5, on whichis fixed a worm ('5, that is equal in diameter to the internal diameterof the cylinder. One end of the worm-shaft 5 projects through the cap 1and has fixed thereon a pinion 7 and a crank 8. Pivotally attached tothe upper side of the cylinder, as at 9, is one end of a bracketarm 10,on the opposite end of which is journaled a gear-wheel 11. Thebracket-arm 10 is adapted to rest in a forked support 12, and p whenseated in said support the pinion 11 is in engagement with thegear-wheel 7. By

the use of said forked support I am enabled to mount the gear-wheel 11upon a single bracket-arm 10 to prevent lateral movement of said arm andthe gear-wheel carried thereby and to so support the wheel 11 withrespect to the pinion 7that binding action between the said wheel andpinion is avoided. In other words, the forked support 12 serves toprevent lateral displacement of the gearwheel 11, as Well as to preventthe weight of said Wheel from coming on the pinion 7. The gear-wheel 11is graduated into twenty parts, as shown, and an index-hand 13 is fixedon the end of the bracket-arm 10 and is adapted to indicate thefractions of a pound on the gear-wheel 11. A smaller toothed wheel 141isjournaled on the end of a bracket-arm 15, fixed on the cylinder, andis graduated into twenty parts, as shown. A tooth 16 is fixed on theface of the geanwheel l1 and is adapted to engage the teeth formed onthe periphcry of the wheel 14. The fixed index-hand 13 also serves toindicate upon the wheel 14 the number of pounds registered. The saidhand therefore serves the double purpose of indicating upon the wheel 14the number of units of measurement and upon the wheel 11 the number offractional parts of a unit of measurement.

In operation the material is placed in bulk in a bin or tank 17, formedon the top of the hopper 2, and feeds down-into the cylinder by gravity.By turning the crank 8 the worm is rotated in the cylinder and operatesto force the material forward in a uniform manner toward and out thedischarge-spout 3. In practice the worm is formed of such pitch and sizethat a given nu mberof turns will measure and discharge exactly onepound of materialsuch as coffee, for example. Let it be assumed thatfour complete revolutions of the worm will measure and discharge exactlyone pound of coffee, then the gear-wheel 11 will be made four times thesize of the pinion 7, so that when the worm has been rotated four timesto measure and discharge a pound of coffee the gear-wheel 11 will berotated once and will indicate one pound on its graduated face; butshould the worm be rotated but once, the gear-wheel 11 will then beturned but onefourth of a revolution and will indicate the number 5 orfive-twentieths or one quarter of a pound. At the end of each completer0- tation of the gear-wheel 11 the tooth 16 will engage the teeth ofthe wheel 1% and turn said wheel a distance equal to one tooth and willindicate on the graduated face of the wheel 14: one pound. The wheels 11and 14 being graduated into twenty divisions, as before described, thewheel 11 will indicate measurements from one-twentieth of a pound up toa pound and the wheel ll from one pound to twenty pounds.

By mounting the wheel 11 on a pivoted bracket-arm, as described, shouldit become necessary to set or change the wheel 11 it is merely necessaryto raise the bracket-arm up, and thus throw the wheel 11 out ofengagement with the other two wheels, when it can be freely rotated asdesired.

By making the cap i-removable access may be had to the interior of thecylinder for cleaning or repairing the parts.

By means of the device constructed in the manner above described thematerials may be stored in bulk and are at all times instantly ready formeasuring. The materials may be automatically measured and discharged inany given quantities with despateh and accuracy and without liability ofwaste and the measurements be automatically indieated.

Having described my invention, what I claim is In a measuring andregistering machine,the combination with a cylinder, having openings forsupplying the material to be measured thereto, and for discharging ittherefrom, a feed screw or worm extending through said cylinder andmeans for operating it, and a pinion secured to said screw or worm, of aforked support, a pivoted bracket-arm adapted to rest upon said supportbetween the branches of the fork thereon, and a graduated gear-wheelcarried by said arm and adapted to mesh with said pinion, as and for thepurpose set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
